Hormones are molecules released by a group of cells in the body that influence the behavior of another group of cells. Hormones are the chemical signals of the endocrine system, the group of glands that, along with the nervous system, controls the body's responses to internal and external stimuli. Hormones are carried to their target cells in the bloodstream. All hormones bind at the target cell to a specific receptor, a protein made by the target cell. When the hormone binds to the receptor, it causes a change in the receptor's conformation , or shape.
